Editorial Note 2016100458 There are 3 pages of Description A nail knocking assistance tool Technical field This utility model relates to a nail knocking assistance tool. Background technology During construction, the hammer is often used to knock in the nail, and drive the nail into an object. But the thrust face of nail is small. To avoid the nail inclining, the operator needs to hold the nail with hand and then uses the hammer to knock in the nail. Such operation mode may easily hurt the hand of an operator. Invention content The technical problem to be solved by this utility model is to provide a nail knocking assistance device. With this device, corresponding calibration sleeve can be chosen according to the model of nails. The calibration sleeve is used to locate the nail. Then, hammering force is imposed above the head to knock in the nail. In the whole process, the operator does not need to hold the nail in hand. This avoids harm to the operator. To solve the above problem, this utility model adopts the following technical proposal: A nail knocking assistance tool includes the head. Threaded hole is set at the right end of head. Handle rod is installed in the threaded hole. The handle rod has thread part which fits with the threaded hole. The handle is at one end of handle rod away from the head. Sliding chute is set in the head. Left sliding block and right sliding block are slidingly installed in the sliding chute. Elastic element is installed respectively between the left sliding block and the end wall of sliding chute and between the right sliding block and the end wall of sliding chute. Access port which is interlinked with the sliding chute is set at the head where the left and right symmetry axis of sliding chute is located. Quitting slope and loading slope are set at the end face where the left sliding block and the right sliding block face each other. Optimally, the head is made of stainless steel. Optimally, the top and bottom of head are of circular arc transition at the outer ring. Optimally, anti-skidding particles are evenly distributed on the outer surface of handle. Beneficial effects of this utility model are as follows: the device can clamp the nail between the left sliding block and the right sliding block from the access port. The nail can be knocked in through imposing hammering force above the head. In the whole process, the operator does not need to hole the nail in hand, which avoids the harm to the operator. Since quitting slope and loading slope are set on the left sliding chute and the right sliding chute, the nail can be knocked in and taken out easily. The structure of this device is simple, and its cost is low. Besides, it is easy to operate. Therefore, it is suitable for promotion.
Descriptions of attached figures To explain the implementation example or the technical proposal more clearly, the attached figure used in the implementation example or the technical proposal is simply introduced as follows. Obviously, the attached figure just describes some implementation examples of this utility model. For common technical personnel in this field, they can gain other attached figures under the precondition of no creative work. Fig.1 is structure diagram of this utility model. Detailed implementation way The optimized implementation example of this utility model is elaborated as follows in combination of the attached figure so that the advantages and features of this utility model can be easily understood by technical personnel in this field and the protection scope of this utility model can be defined more clearly and explicitly. According to Fig.1, a nail knocking assistance tool includes the head 1. Threaded hole is set at the right end of head 1. Handle rod 4 is installed in the threaded hole. The handle rod 4 has thread part 411 which fits with the threaded hole. The handle 5 is at one end of handle rod 4 away from the head 1. Sliding chute 15 is set in the head 1. Left sliding block 11 and right sliding block 12 are slidingly installed in the sliding chute 15. Elastic element 17 is installed respectively between the left sliding block 11 and the end wall of sliding chute 15 and between the right sliding block 12 and the end wall of sliding chute 15. Access port 16 which is interlinked with the sliding chute 15 is set at the head 1 where the left and right symmetry axis of sliding chute 15 is located. Quitting slope 14 and loading slope 13 are set at the end face where the left sliding block 11 and the right sliding block 12 face each other. An as optimal implementation example, the head 1 is made of stainless steel. An as optimal implementation example, the top and bottom of head 1 are of circular arc transition at the outer ring. An as optimal implementation example, anti-skidding particles (not shown) are evenly distributed on the outer surface of handle 5. Beneficial effects of this utility model are as follows: the device can clamp the nail between the left sliding block and the right sliding block from the access port. The nail can be knocked in through imposing hammering force above the head. In the whole process, the operator does not need to hole the nail in hand, which avoids the harm to the operator. Since quitting slope and loading slope are set on the left sliding chute and the right sliding chute, the nail can be knocked in and taken out easily. The structure of this device is simple, and its cost is low. Besides, it is easy to operate. Therefore, it is suitable for promotion.
The above content is a specific implementation way of this utility model. However, the protection scope of this utility model is not limited to this. Any change or replacement without creative work shall be covered in the protection scope of this utility model. Therefore, the protection scope of this utility model shall be subject to that defined in the claim.
