When the two terminal boards are fully attached, the screws to be installed are inserted into the corresponding screw holes and tightened to realize the installation of the two terminal boards. . Afterwards, adjusting the ratchet device adjustment lever can change the working direction of the ratchet in the ratchet stop device, and toggle the ratchet device adjustment lever so that it can rotate in the opposite direction, and rotate the handle in the opposite direction to drive the upper and lower clamping clips to separate. The device exits the wiring board and completes the installation of the remaining screw rods. The screw hole positioning rod of the wiring board is equipped with a variety of diameter specifications, which can be disassembled and replaced to meet the requirements of on-site use. The device is equipped with positioning rods made of different specifications according to the diameter of the commonly used screw rods for easy use.

The portable wiring board bolt installation auxiliary device described in the utility model effectively solves the problem of lack of auxiliary tools when installing the wiring board bolts in the current electric power maintenance project, and can conveniently and quickly penetrate the screw rod into the corresponding position of the two wiring boards to be installed. screw holes.

Detailed ways

Specific embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

A portable wiring board bolt installation auxiliary device, as shown in Figure 1, includes a housing 18, the left and right sides of the housing 18 are respectively installed with rack I11 and rack II12 through chute, and the installation between rack I11 and rack II12 The clamping gear 13, the rotation of the clamping gear 13 respectively drives the rack I11 and the rack II12 to move up and down. The upper clamping fixture 1 and the lower clamping fixture 2 opposite to each other are installed on the same side of the housing 18, and the upper clamping fixture 1 and the lower clamping fixture 2 are driven by the rack I11 or the rack II12. The clamping gear 13 is fixedly installed on the clamping rotating shaft 17, the housing 18 is equipped with a ratchet stopper 14, the inner end of the tightening rotating shaft 17 drives the ratchet 14-1 of the ratchet stopper 14 to rotate, and its outer end is connected to the rotating handle 16 , the ratchet stop device 14 makes the clamping gear 13 only rotate in one direction each time; the ratchet stop device 14 changes the stop direction of the ratchet 14-2 by adjusting the ratchet device to the lever 15, and the ratchet 14-1 rotates forward and reverse , while realizing the positive direction rotation of the clamping gear 13 .
