Problems solved by technology

[0004] Although the above-mentioned tool chuck used for hammer-drilling devices can realize the installation and locking of the tool head, it also needs to rotate the adjustment sheath while moving the adjustment sheath in the axial direction when the tool head is disassembled, which brings great inconvenience to the operator. Inconvenience

Embodiment Construction

[0049] Reference figure 1 The present invention discloses a chuck and a hammer drill power tool using the chuck. In a preferred embodiment of the present invention, the hammer drill power tool is an electric hammer. The hammer drill type power tool includes a tool body 1, a motor 200 and a transmission mechanism 100 housed in the tool body 1. A handle 11 is provided at the rear of the tool body 1 (the right side in the figure is defined as the rear), and the chuck 2 is installed At the front of the tool body 1 and connected with the transmission mechanism 100. When the motor 200 is driven, the rotational torque output by the motor is transmitted to the chuck 2 through the transmission mechanism 100, and the tool head 9 is driven to rotate. The motor 200 may be a motor, and the transmission mechanism 100 may be a gear reduction transmission mechanism or a cam transmission mechanism.

Abstract

A collet, used to accommodate and clamp the tool head inserted from the outside, including a sleeve, used to accommodate the tool head inserted from the outside, the sleeve is provided with a long groove radially penetrating through the wall of the sleeve; locking a block, accommodated in the long groove and can move radially along the sleeve to lock or release the tool head; a sheath assembly, sleeved outside the sleeve and movable axially relative to the sleeve; and sleeved There is a rotating sleeve between the sleeve and the sheath assembly and can be respectively matched with the locking block and the sheath assembly. When the locking block is pushed axially, the locking block drives the rotating sleeve to rotate to allow the locking block diameter When the sheath assembly moves axially, the sheath assembly drives the locking block to rotate to allow the locking block to move radially. A power tool includes a tool body, a motor installed in the tool body, a transmission mechanism connected to the motor, and a collet connected to the transmission mechanism, and the collet is the above-mentioned collet.

Description

Technical field [0001] The invention relates to a chuck and a power tool using the chuck, in particular to a chuck with a quick clamping release tool head and a hammer drill power tool using the chuck. Background technique [0002] Traditional hammer drill power tools, such as electric hammers, have a housing, a drive shaft arranged in the housing, and a chuck connected to the drive shaft. The chuck is used to clamp the tool head. The tool head is installed in the chuck to limit the axial movement by inserting the driving shaft of the tool rotation movement and the locking block inserted into the locking groove of the tool head. [0003] US Patent No. 4,626,146 discloses a tool chuck for hammer drill devices, including a guide tube for installing cylindrical tools, and an adjusting sheath that is arranged around the guide tube and can move and rotate axially relative to the guide tube , Several locking elements mounted on the guide tube. The guide tube is provided with an opening...
