Compared with the prior art, the utility model, have following advantage and effect:

1. the utility model discloses do not need the manual operation bolt, save time to do not worry that the maloperation leads to the work arm frame to damage.

2. In terms of stress, when the arm bracket supports the fixed arm, the lower part of the working arm is stressed, and the working arm is mainly stressed on the fixed arm; when the arm bracket supports the movable arm, the movable arm is stressed up and down, the upper part of the fixed arm is stressed, and the arm bracket structure of the working arm is easily damaged if the stress directions of all structures of the working arm are different; the utility model provides an arm bracket supports on the fixed arm, and each structure atress condition is better in the work arm to strike lessly the fixed arm during the receipts vehicle-hour, be difficult for causing the damage to the work arm.

3. If the original hydraulic pressure of work arm lock trouble became invalid, the utility model discloses can give other people certain reaction time for work arm provides structural anticreep effect, prevent that the digging arm from directly deviating from, cause bodily injury and loss of property.

4. The utility model discloses simple structure, it is with low costs, just can reach the anticreep effect through simple structure, convenient to use, the range of application is wide.

Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

Examples are given.

Referring to fig. 1 to 3, the simple working arm anti-drop device in the present embodiment includes a bolt assembly 2, an arm bracket 3, a stopper 4, and a hook 1 for limiting the stopper 1; the hook body 1 is fixed on the arm bracket 3 through a bolt component 2; the stop block 4 is fixed on the movable arm 5-2 of the working arm 5; the hook body 1 is matched with the stop block 4; the arm bracket 3 comprises a base 31, a support column 32, a fixing table 33 for fixing a fixing arm 5-1 of the working arm 5 and a mounting plate 35 for mounting the hook body 1; the supporting column 32 is fixed on the base 31; the fixed table 33 is fixed on the support column 32; the mounting plate 35 is fixed to the side of the support column 32.
