The swingable member includes a slide guide surface configured to come into sliding contact with a slide surface of the media cassette upon the insertion and pulling of the medium cassette.

The invention discloses bridge construction equipment which comprises a sliding contact chamber that is arranged in an electric contact seat. The right end surface of the electric contact seat is provided with hanging rods which are symmetrically mounted in a front-and-back direction. A hanging hole which is used for hanging the electric contact seat is arranged between the lower side of the hanging rod and the electric contact seat. The back side of the left end surface of the electric contact seat is provided with a jack which is communicated with the sliding contact chamber. The right end wall of the sliding contact chamber is provided with a sliding contact trough which extends in the front-and-back direction. The right side of the back end wall of the sliding contact trough is provided with an electric contact column. The left side of the back end wall of the sliding contact chamber is provided with a through hole which is communicated with outside of the electric contact seat ata position which is near to the jack. The right end wall of the sliding contact chamber is provided with a first locking trough in front of the locking contact trough. The bridge construction equipment has a simple structure. A connecting board is frontward pushed through a handheld part, and the connecting board frontwards pushes the sliding contact block, thereby realizing locking of the slidingcontact block.

A catalyst extrusion molding machine convenient to maintain comprises an annular semi-circular pipe, the outer edge of the top side of the annular semi-circular pipe is fixedly connected with the lower end of a barrel coaxial with the annular semi-circular pipe, the inner edge of the top side of the annular semi-circular pipe is rotationally connected with the lower end of an inner pipe coaxial with the annular semi-circular pipe through a sealing bearing, and the upper end of the inner pipe is rotationally connected with the top of the barrel through a sealing bearing; and the outer peripheryof a first spiral blade is in sliding contact fit with the inner periphery of the barrel, the diameter of elastic rubber balls is larger than the thread height and thread pitch of the first spiral blade, a feeding port is formed in the top side of the barrel, and a plurality of fine holes are evenly formed in the bottom of the annular semi-circular pipe. The catalyst extrusion molding machine convenient to maintain is simple in structure and ingenious in conception, raw materials can be circularly stirred up and down through a double-screw structure, the situation that the raw materials are hardened and bonded to the spiral blade is fundamentally reduced, therefore the elastic rubber balls rub against the spiral blade are circularly, thus, the elastic rubber balls rub off the raw materials bonded to the spiral blade, cleaning of the spiral blade is achieved, market requirements can be met, and the catalyst extrusion molding machine is suitable for popularization.

A washer is held by being sandwiched in an axial direction by a pinion and a holder. Here, although the washer is inexpensive, it has high planar accuracy. Then, by sandwiching the washer in the axial direction between the pinion and the holder, a metal surface of the inexpensive washer with high planar accuracy can be used as a contacting surface that contacts a holder side slide-contacting surface directly. Furthermore, another metal surface of the washer can also be directly contacted to a pinion side slide-contacting surface. Thereby, wear caused by a slide-contacting rotation of the holder can be reduced without raising costs of parts and processing in the starter that adopts a pinion shift structure.
