TWI289096B - Improved power output of screwdriver tool - Google Patents

Abstract

The present invention relates to an improved power output of screwdriver tool, which has a transmission device composed of an elastic member, a transmission rod and a brake member and disposed within a hollow space of the screwdriver body enclosed by an inner periphery, a grip composed of two half-separated handles and pivotally disposed on an outer periphery of the screwdriver, link members disposed between both sides of the grip and the brake member. Thus, when the two handles are repeatedly pressed for operation, the power of a locking member is driven to output with a low speed and a high torque.

Description

!289〇96 V. INSTRUCTIONS (1) [Technical field to which the invention belongs] The present invention is a kind of screwdriver which is modified by the torque of the J-tool when it is used.

When the torque required for large locking is required, it is impossible to 2) It is more obvious that the inconvenience is not normal. The sub-locking screw or the lock output drives the screw-solid component. Generally, the screw-locking component of the screw-setting component is locked. The Y-port component of the field is opened for the lock component, and the pressure is not required. The state of the horizontal state drive lock force output is:;m standard, the customary creation of the twist for the user for each time white s target plus pressure pre-locking components, in view of this, the need for good. Manufacturing experience, in order to improve the above-mentioned shortcomings in the research and development of the relevant industries in the past year. Eight power transmission improvement 』 [three, the content of the invention] The main purpose of this description is to provide a "improvement", which is the driver of the tool = the power output of the tool to apply to different players or sales $ 1, two rounds Operation change, 豕u mouth or lock the entry of the workpiece lock operation. In order to achieve the above-mentioned effects and purposes, the "force output improvement" of the present invention is composed of a sub-body, a grip, and a moving shaft. Wherein, the inner edge of the screwdriver is hollow, 2 and interlocking, and the outer edge is suitable for the handle pivot group, and the second transmission device is arranged with a sliding groove; the handle is composed of two The half-section of the button is =1 long axis, and each of the two ends of the inner edge of the handle is provided with a pivoting portion, the political & mouth composition /, the brother a pivotal system and
