[0002] The steel bar clamping rod is a device suitable for clamping steel bars during steel bar processing. Today's steel bar clamping equipment is large in size and difficult to use in a small space. It has poor flexibility and cannot be retracted. It is time-consuming and laborious to use. It requires manual locking of the clamp. The workers have high work intensity and low efficiency. The clamping force is uncontrollable and cannot be freely adjusted for steel bars of different diameters. It is easy to cause the steel bar to be damaged due to excessive clamping force. The search of existing patents did not find any relevant patents specifically for steel bar clamping rods. The existing technology has the following inconveniences when clamping steel bars:

[0003] 1. Today's steel bar clamping equipment is large in size, difficult to use in a small space, has poor flexibility and cannot be retracted, so there is an urgent need for a steel bar clamping rod that is easy to carry and retractable;

[0004] 2. It is time-consuming and laborious, and requires manual locking of the clamp. The workers have high work intensity and low efficiency, so a labor-saving steel bar clamping rod is urgently needed;

[0005] 3. The tightening force is uncontrollable and cannot be freely adjusted for steel bars of different diameters, which may cause damage to the steel bars due to excessive clamping force. Therefore, a steel bar clamping rod with controllable clamping force to avoid damage to the steel bars is urgently needed. Utility Model Content

[0010] Preferably, the clamping sleeve is designed to be cylindrical.

[0011] Preferably, the handheld handle is of cylindrical design.

[0012] Preferably, the restraining head adopts a hollow frustum design.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model uses a tightening motor to drive the tightening gear to rotate, and the tightening gear drives the tightening bevel nut to rotate. The clamping structure is compact and small in size. Applying it to the steel bar clamping tool can significantly reduce the overall size and weight of the tool. This compact design makes the tool more portable and easy to operate in a small construction space, improving the flexibility of the tool.

[0015] 2. The utility model uses a tightening motor, which drives the tightening gear to rotate, and the tightening gear rotates to tighten the bevel nut to drive the gear teeth around it to rotate. The tightening nut drives the clamping die to extend and retract. When the clamping die is obliquely installed and moves on the constraint head, the three clamping dies move centripetally to clamp the steel bar. In this way, the power of the motor can be used to easily achieve a large clamping force without applying a large amount of manpower. It can significantly reduce the labor intensity of workers and improve work efficiency;

[0016] 3. The tightening method using a tightening motor can be adjusted according to the diameter of the steel bar and the required clamping force. When clamping the steel bar, if the clamping die is clamped and the clamping requirement is met, the clamping die stops extending and retracting, and the bevel nut and the tightening gear stop rotating to generate resistance, which can effectively avoid the problem of steel bar clamping caused by excessive force.

[0024] Example

[0025] See also Figure 1-3 , the utility model provides a technical solution:

[0026] A steel bar clamping rod with adjustable length comprises a clamping sleeve 1, a hand-held handle 2 is installed at the rear of the clamping sleeve 1, a clamping button 3 is arranged on the hand-held handle 2, a telescopic sleeve 9 is installed at the front end of the hand-held handle 2, a restraining head 5 is arranged at the front end of the clamping sleeve 1, a clamping die 6 is arranged in the middle of the restraining head 5, a tightening bevel nut 4 is installed at the rear of the restraining head 5, and a tightening gear 7 is installed at the rear of the tightening bevel nut 4 to mesh with the tightening gear 7. A tightening motor 8 is connected to the rear of the tightening gear 7. The clamping sleeve 1 adopts a cylindrical design. The hand-held handle 2 adopts a cylindrical design. The restraining head 5 adopts a hollow frustum design. Three clamping dies 6 are arranged.

[0027] Compare Projects Traditional clamping method New clamping equipment Work efficiency Manual clamping is inefficient Electromechanical clamping efficiency increased by 56% Space Occupancy The space it takes up is too big to use Small footprint and 50% more flexibility Steel bar clamping injury There are many cases of clamping due to uncontrollable torque Controlled torque pinch injuries reduced by 55%

[0028] By comparing the above table, it can be seen that compared with the traditional clamping method, the utility model uses a tightening motor to drive the tightening gear to rotate, and the tightening gear drives the tightening bevel nut to rotate. The clamping structure of the electric drill is compact and small in size. It is applied to the steel bar clamping tool to significantly reduce the overall size and weight of the tool. This compact design makes the tool more portable and easy to operate in a small construction space, improves the flexibility of the tool, and a retractable telescopic sleeve is provided on the top of the hand-held handle to meet different space requirements, and the flexibility of the equipment is increased by 50%. In the utility model, by using a tightening motor, the tightening motor drives the tightening gear to rotate, and the tightening gear rotates to the tightening bevel nut to drive the gear teeth around it to rotate, and the tightening nut is tightened to drive the clamping die to retract, and when the clamping die is obliquely installed and moves on the constraint head, the three clamping dies move centripetally to clamp the steel bar. In this way, a larger clamping force can be easily achieved by using the power of the motor. It can significantly reduce the labor intensity of workers, and the efficiency of clamping without manpower is increased by 50%. The tightening method using a tightening motor can be adjusted according to the diameter of the steel bar and the required clamping force. When clamping the steel bar, the clamping die stops extending and retracting after the clamping requirement is met. The bevel nut and the tightening gear stop rotating to generate resistance, which can effectively avoid the problem of steel bar clamping caused by excessive force and reduce the steel bar clamping situation by 55%.

[0029] When the utility model device is used, the tightening motor is started to drive the tightening gear to rotate. The tightening gear meshes and drives the tightening bevel nut to rotate. The tightening bevel nut is provided with a thread matching the gear teeth. When the tightening bevel nut rotates, the gear teeth around it also rotate accordingly. The gear teeth mesh with the racks on the clamping die. The clamping die is obliquely mounted on the restraining head. As the gear teeth rotate, the clamping die moves telescopically under the guidance of the restraining head. The three clamping die move centripetally, gradually approach and finally clamp the steel bar located in the center. By adjusting the speed and torque of the motor, the size of the clamping force can be accurately controlled.

[0030] The utility model adopts a clamping structure design similar to that of an electric drill. The compact design significantly reduces the overall size and weight of the steel bar clamping tool, improves the portability and flexibility of the tool, and is convenient for operation in a narrow construction space. A retractable telescopic sleeve is arranged on the top of the hand-held grip, which can be applied to different use space requirements. The utility model uses a tightening motor to drive the tightening motor to rotate, and the tightening gear rotates to the tightening bevel nut to drive the gear teeth around it to rotate. The tightening nut is tightened to drive the clamping die to extend and retract. When the clamping die is obliquely mounted and moves on the constraint head, the three clamping die move centripetally to clamp the steel bar. In this way, the power of the motor can be used to easily achieve a large clamping force without applying a large amount of manpower, which can significantly reduce the labor intensity of the workers and improve work efficiency. In addition, by using a tightening motor, it can be adjusted according to the diameter of the steel bar and the required clamping force. When the clamping die is clamped, if the clamping requirement is met, the clamping die stops extending and retracting, and the tightening bevel nut and the tightening gear stop rotating to generate resistance, which can effectively avoid the problem of steel bar clamping caused by excessive force.
