Problems solved by technology

[0002] For the battery packs in the existing electric tools that use batteries as the power source, the cell assembly is different due to the size of the cells from different manufacturers, and a single battery holder corresponds to a single cell. Some holders are used on some holders, so that the power tool is limited when using the battery; in addition, after the battery holder is used for a long time, the friction coefficient between the battery holder and the battery will decrease accordingly, so the battery is in There will be looseness in the battery holder, which will affect the normal power supply of the battery pack to the electric tool, thus affecting the normal operation of the electric tool

Embodiment Construction

[0022] The following is Figure 1-11 The represented embodiment further describes the present invention:

[0023] It includes an upper cage 1 and a lower cage 2. The upper cage 1 is equipped with 20 battery cell slots A1.1 for the battery cells 3, and the lower cage 2 is equipped with 20 battery cell slots B2 for the battery cells 3. 1. Each cell slot A1.1 of the upper cage 1 is provided with a clamping structure A1.2 for clamping one end of the cell 3; each cell slot B2.1 of the lower cage 2 is provided with a clamping structure A1.2. Clamping structure B2.2 at the other end of the core 3. The clamping structure A1.2 of each cell slot A1.1 of the upper cage 1 is provided with three evenly distributed elastic clamping feet A1.3 on the peripheral wall of each cell slot A1.1; Each cell slot B2.1 of the lower cage 2 is provided with a clamping structure B2.2, and the peripheral wall of each cell slot B2.1 of the lower cage 2 is provided with three uniformly distributed elastic ...

Abstract

The invention relates to a battery retainer with a battery cell clamping structure, and belongs to the technical field of a battery packet for an electric tool. The battery retainer comprises an upper retainer (1) and a lower battery retainer (2), wherein the upper battery retainer (1) is provided with a plurality of battery cell grooves A (1.1) for installing battery cells (3); the lower battery retainer (2) is provided with a plurality of battery cell grooves B (2.1) for installing the battery cells (3). The battery retainer is characterized in that each battery cell groove A (1.1) of the upper retainer (1) is provided with a clamping structure A (1.2) for tightly clamping one end of the battery cell (2); each battery cell groove B (2.1) of the lower retainer (2) is provided with a clamping structure B (2.2) for clamping the other end of the battery cell (3). The retainer has the advantages that the battery retainer is enabled to still tightly clamp the battery cell after the use for a long time; in addition, the battery cell with the small diameter can be mutually changed to be used on the battery retainer, so that the selection range of the electric tool using the battery as a power supply on the battery cell is expanded; the cost of the battery cell is reduced.
