Description

Technical Field

[0001] The present application relates to the field of construction and building, and in particular to a fixing device for construction. Background Art

[0002] At construction sites, such as home decoration sites or construction sites, it is necessary to perform operations such as marking and punching on certain wood boards. To ensure the accuracy of the operation, workers often hold down the wood boards to fix them, and then work on the wood boards. However, the manual fixation method is not very stable, and after the workers fix the wood boards with one hand, they can only use the tools with their dominant hand to operate. When encountering complex situations (such as when punching, the impact force is large, the fixation degree of one hand is not enough, and the wood board may move), the operation is inconvenient, which affects the work efficiency and needs to be improved. Utility Model Content

[0003] In order to improve the fixing stability of the wood board, the present application provides a fixing device for construction.

[0009] Optionally, rubber pads are provided on opposite sides of the first clamping plate and the second clamping plate.

[0010] By adopting the above technical solution, a rubber pad is provided to abut against the material when the material is clamped, so as to prevent the material from being damaged when it is clamped and fixed.

[0011] Optionally, the main cylinder is provided with a side plate, and the side plate is provided with a rotating hole for accommodating the adjusting screw.

[0012] By adopting the above technical solution, a rotating hole is provided on the adjusting screw rod, so that the adjusting screw rod can rotate on the main cylinder body.

[0013] Optionally, a mounting protrusion is provided on the main cylinder body, and a mounting groove for accommodating the mounting protrusion is opened on the side plate.

[0014] By adopting the above technical solution, the mounting protrusions and the mounting grooves are matched with each other, so that the side plate can be easily mounted on the main cylinder.

[0015] Optionally, a limiting protrusion is provided on the adjusting screw, and the limiting protrusion abuts against the side wall of the side plate.

[0016] By adopting the above technical solution, the limiting protrusion is arranged to abut against the side plate, thereby preventing the adjusting screw from moving in a direction away from the first clamping plate.

[0017] Optionally, a bearing is provided on the adjusting screw, the central axis of the bearing is the same as the central axis of the rotating hole, and the bearing is in contact with the side plate.

[0018] By adopting the above technical solution, the bearing is arranged to increase the stability of the rotation of the adjusting screw, making the rotation of the adjusting screw smoother.

[0019] Optionally, the adjusting screw is provided with an adjusting handle, and the adjusting handle is used to rotate the adjusting screw; the adjusting screw is inserted with a limit rod, and the limit rod is used to fix the adjusting handle on the adjusting screw, and the bearing is located between the side plate and the bearing.

[0021] Optionally, a limit block is provided on the adjusting screw, and two ends of the limit block are respectively fitted with the bearing and the limit rod, and the bearing, the limit block and the limit rod are arranged in sequence on the adjusting screw.

[0022] By adopting the above technical solution, a limit block is provided to cooperate with the bearing and the limit rod to prevent the adjusting screw from moving toward the direction close to the first clamping plate, so that the adjusting screw can only rotate.

[0023] Optionally, an anti-slip cover is provided on the adjustment handle.

[0024] By adopting the above technical solution, an anti-slip sleeve is provided to prevent the worker from slipping when turning the adjustment handle, so that the worker can firmly grasp the adjustment handle.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The adjusting screw adjusts the position of the sliding rod through the threaded hole. When the adjusting screw is turned, the adjusting screw rotates in the threaded hole. Since the sliding rod does not rotate in the main cylinder, the sliding rod will be driven to move. When the wood board (other materials are also acceptable) needs to be fixed, the adjusting screw is turned to move the sliding rod toward the main cylinder, so that the first clamping plate and the second clamping plate are close to each other, thereby clamping the wood board and the workbench where the wood board is placed, so that the wood board is fixed. After that, the worker can operate on the wood board with both hands, and the fixing device has high stability in clamping and fixing the wood board on the workbench, and will not be affected by the impact force of punching holes; the construction fixing device is convenient for fixing the wood board and has high fixing stability for the wood board;
