3results about How to "Effort-saving clamping" patented technology

The utility model relates to the technical field of anti -skidding of climbing car, and disclose climbing car anti -skidding subassembly, including climbing car frame, the bottom four corners of climbing car frame all are fixedly installed with universal wheel, the bottom both sides of climbing car frame all are equipped with anti -skidding mechanism symmetry, the anti -skidding mechanism includes two concave plates, two the inside of concave plate all are equipped with two slide rails, two the inside of slide rail all slide installation has the clamping plate, through setting up the cooperation of anti -skidding mechanism and drive mechanism, when positive and negative rotation motor drive adjusting lead screw rotates, the screw hole disc drives drive plate to push concave plate and move along the guide rail to the universal wheel, the gyro wheel on clamping plate rolls along the taper block inclined plane, and the thrust of taper block inclined plane forces clamping plate to overcome the tensile spring elasticity and clamps the universal wheel, both limit its rolling, and prevent axial rotation, avoid climbing car operation to slip and shake, improve stability and security.

The utility model provides a firm clamping reaming lever which comprises a handle (1), a fixed clamping block (2) and a movable clamping block (3), the fixed clamping block (2) is an L-shaped block, a vertical V-shaped groove (6) is formed in the middle of the long edge of the fixed clamping block (2), and threaded counter bores (7) perpendicular to the V-shaped groove (6) are symmetrically formed in the same horizontal positions of the two sides of the V-shaped groove (6); the movable clamping block (3) and the fixed clamping block (2) are the same in shape and size, the space defined by the movable clamping block (3) and the short side of the fixed clamping block (2) which are oppositely and reversely combined is a cuboid, and the V-shaped grooves (6) in the middles of the long sides of the two L-shaped blocks are combined to form a jaw used for clamping a screw tap (9) or a square cylinder at the tail of a reamer. Due to the fact that the corresponding threaded holes are formed in the combination faces of the movable clamping block (3) and the fixed clamping block (2), the clamping bolt (4) is controlled through a tool to enable the movable clamping block (3) to be close to or away from the fixed clamping block (2), clamping is firm and labor-saving, and students can operate the clamping device more conveniently.

The outdoor barbecue shovel assembly tool comprises a bottom plate, a shovel head baffle is arranged at one end of the bottom plate, a push block is arranged at the other end of the bottom plate, and a first linear reciprocating motion mechanism for controlling the push block to move close to or away from the shovel head baffle is arranged on the push block. A left side plate and a right side plate which are arranged on the bottom plate are arranged between the shovel head baffle and the push block, a positioning groove extending front and back is formed between the right side plate and the left side plate, a supporting part close to the shovel head baffle is arranged in the positioning groove, and a pressing block capable of stretching into the groove is arranged above the positioning groove. The pressing block is provided with a second linear reciprocating motion mechanism which controls the pressing block to move close to or away from the positioning groove. The assembly tool has the advantages of being convenient to clamp and labor-saving in assembly, and is complete in overall function and high in practicability.
