The structure is simple, and the entire device is easy to carry.

[0038] During use: the limit component 102 is locked on the limit plate 101 through the set locking component 103, and then the position of the limit component 102 is adjusted to facilitate stable support of the bottom surface of the bolt at different distances; then the limit component 102 is pressed against the bottom surface of the bolt, and the clamping plate 203 is pressed against the plate for installing the bolt. By locking the locking component 202 and the plate for installing the bolt, the overall installation of the bolt auxiliary mechanism is realized, and the bottom surface of the bolt is clamped, freeing the user's hand to hold the bolt and avoiding the installation operation of using both hands.

[0039] Example 2

[0040] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that the overall fixing and limiting of the limiting assembly 102 is achieved through the cooperation between the clamping portion 103d and the rack 101a.

[0041] Preferably, the limiting assembly 102 includes a moving block 102a slidably disposed on the limiting plate 101, a supporting plate 102b disposed on the moving block 102a, and a fence 102c disposed on the supporting plate 102b. The supporting plate 102b is provided to press the bottom surface of the bolt, and the fence 102c is used to limit the bottom surface of the bolt. When the locking assembly 202 is locked, the fence 102c always limits the bottom surface of the bolt, thereby avoiding the separation of the supporting plate 102b and the bottom surface of the bolt, and making the limiting more stable.

[0042] Furthermore, the moving block 102a is provided with a through hole 102a-1, and the moving block 102a is provided with a mounting opening 102a-2 connected with the through hole 102a-1; the mounting opening 102a-2 is provided with a slide groove 102a-3.

The bolt auxiliary mechanism is stably pressed against the bottom surface of the matching unit 400 by the auxiliary unit 200, so that the auxiliary unit 200 can be operated by one hand. The matching unit 400 includes a mounting plate 401 and a clamping bolt 402 arranged on the mounting plate 401.

[0050] The fixing unit 300 includes a lifting plate 301 slidably arranged on the connecting plate 201, a pressing plate 302 arranged on the lifting plate 301, a flange plate 303 arranged on the lifting plate 301, a guide block 304 arranged on the lifting plate 301, a spring 2 305 arranged on the guide block 304, and an anti-slip assembly 306 arranged on the bottom surface of the lifting plate 301. The fixing unit 300 moves to the top of the mounting plate 401, and then is pressed on the mounting plate 401 by the pressing plate 302, and at the same time, the auxiliary unit 200 and the limiting unit 100 move downward in the vertical direction until the limiting unit 100 is located below the clamping bolt 402, at which time the auxiliary unit 200 is pushed to move toward the clamping bolt 402, and the supporting plate 102b supports the clamping bolt 402. At this time, the supporting plate 102b and the pressing plate 302 work together to initially limit the entire device on the mounting plate 401, completing the one-handed installation operation of the entire device.

[0051] Preferably, the connecting plate 201 is provided with a strip groove 201a, and the connecting plate 201 is provided with a guide groove 201b connected with the strip groove 201a. The lifting plate 301 slides and rubs against the inner wall of the strip groove 201a, and the guide block 304 is slidably disposed in the guide groove 201b.

The direction of the anti-skid strip 2 306b is different from the direction of the anti-skid strip 1 306a, so that when the lifting plate 301 swings, the directions of the anti-skid strip 2 306b and the anti-skid strip 1 306a are different, thereby reducing the probability of the lifting plate 301 swinging, and the pressing between the lifting plate 301 and the mounting plate 401 is more stable.

[0053] During use: first, move the fixing unit 300 above the mounting plate 401, and then press the pressing plate 302 on the mounting plate 401, while making the auxiliary unit 200 and the limiting unit 100 move downward in the vertical direction until the limiting unit 100 is located below the clamping bolt 402, at this time, push the auxiliary unit 200 toward the clamping bolt 402, and the support plate 102b supports the clamping bolt 402. At this time, the support plate 102b and the pressing plate 302 work together to initially limit the entire device on the mounting plate 401, completing the one-handed installation operation of the entire device; then free up your hand to install the nut on the clamping bolt 402. The entire process can be completed with one hand, which is convenient for people with hand disabilities or only one hand to operate.
