Problems solved by technology

However, these clamping screw devices have a small clamping force on the screws and the use effect is not ideal. The screws are easy to fall off from these clamping devices or the screws are inclined, which brings inconvenience to the screwing process and cannot really improve work efficiency.
Additionally, these devices are difficult to use with power tools

Embodiment Construction

[0124] Such as Figure 1 to Figure 7 Shown is a screw tool 1 according to an embodiment of the invention. This screw tool 1 can be along working direction ( figure 1 Shown by the middle arrow) to drive the screw 100 into the workpiece (not shown in the figure). The screw tool 1 mainly includes a screw supporting device 2 that supports the screw 100 during the working process. During the screw tool 1 screwing the screw 100 into the workpiece, the screw supporting device 2 supports the screw 100 so that the screw 100 is always coaxial with the output shaft axis X of the screw tool 1, and in most cases, the screw 100 is aligned with the surface of the workpiece. The normal direction of 103 is set in parallel. In this way, the screw 100 will not shake or disengage from the working head or deviate from the original position due to the vibration generated by the screw tool 1 during screwing into the workpiece, so that the operator can screw the screw 100 into the workpiece convenie...

Abstract

The invention relates to a screw support device which is used for helping a screw tool for hammering a screw into a workpiece to position the screw. The screw tool is provided with an axis of an output shaft, the screw support device comprises a shell, a support mechanism used for supporting a screw, a driving mechanism for driving the support mechanism to move, and also comprises support legs outside the shell, wherein the support legs are connected with the workpiece in a propping manner and then moves relative to the screw tool, and the driving mechanism responds to the movement of the support legs to drive the support mechanism to move to a position at which the screw is not supported from a position at which the screw is supported. According to the screw support device and the screw tool, the support legs and the surface of the workpiece are connected in a propping manner, so that support units for supporting the screw can loosen the screw automatically.

Description

technical field [0001] The invention relates to a screw supporting device and a screw tool for assembling the screw supporting device. Background technique [0002] In human's daily life, screws are very common and can be applied to many occasions. For example, in the process of house decoration, it is often necessary to connect two originally separate boards together, which is nailed into the boards with screws. Also have for example hanging object on wall or ceiling, also can need to drive into screw on corresponding wall or ceiling. We collectively refer to things that need to be screwed into such plates or walls as workpieces. For the process of screwing into the workpiece, people mainly consider the following factors: 1. Hope that the screw is always nailed into the workpiece with the normal direction of the vertical workpiece surface. 2. When the screw is screwed into the workpiece, it does not need to spend too much energy, which has the effect of saving the physic...
