Description

Technical Field

[0001] This utility model relates to the field of gardening tools, specifically to rakes. Background Technology

[0002] A rake is a tool used in gardening; it is used to rake grass (or leaves).

[0003] The rake includes a handle and a connecting plate mounted on the front of the handle, and multiple rake teeth mounted on the connecting plate, with rake tooth hooks below the rake teeth.

[0004] In practical use, sometimes a rake with sparser teeth is more suitable, and sometimes a rake with denser teeth is more suitable. In the existing technology, the rake handle, connecting plate and rake teeth are all integrated structures, that is, the density between the rake teeth on a single rake is fixed. The density between the rake teeth cannot be adjusted during use, which is inconvenient. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned shortcomings by providing a rake that can adjust the density between the rake teeth and is easy to use—a combined rake.

[0006] The technical solution of this utility model is implemented as follows: A combined rake includes a rake body, which in turn includes a handle and a connecting plate installed in front of the handle, and multiple rake teeth are installed on the connecting plate. The rake teeth have rake tooth hooks below them, and the rake teeth fixedly installed on the connecting plate are fixed rake teeth. The rake also includes an assembly, which includes a connecting rib with a circular cross-section in the transverse direction, and multiple rake teeth are installed on the connecting rib. The rake teeth installed on the connecting rib are movable rake teeth. The connecting plate has a groove that catches most of the side of the connecting rib. This groove is a connecting rib groove. When the connecting rib groove catches the connecting rib, the fixed rake teeth and movable rake teeth are spaced apart, and the movable rake teeth are positioned between two fixed rake teeth.

[0007] Furthermore, a C-shaped pad made of rubber is installed in the connecting rib slot. When the connecting rib slot engages the connecting rib, the C-shaped pad is in a state of holding the connecting rib tightly.

[0008] Furthermore, the connecting plate is also provided with a slot for positioning the movable rake teeth, and the slot is formed by the protrusions on both sides.

[0009] The beneficial effects of this utility model are: such a rake has the advantages of being able to adjust the density between the rake teeth and being easy to use. Attached Figure Description

[0017] Among them: 1. Rake body 11, handle 12, connecting plate 13, fixed rake teeth 14, slot 141, C-shaped pad 15, slot 151, locking protrusion 2. Assembly 21, connecting rib 22, movable rake teeth. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] As shown in the figure, a combined rake includes a rake body 1, which further includes a handle 11 and a connecting plate 12 mounted on the front of the handle. Multiple rake teeth are mounted on the connecting plate, each with a rake tooth hook. Fixed rake teeth 13 are fixedly mounted on the connecting plate. The rake also includes an assembly 2, which includes a connecting rib 21 with a circular cross-section. Multiple rake teeth are mounted on the connecting rib, and movable rake teeth 22 are mounted on the connecting rib. The movable rake teeth have rake tooth hooks. The connecting plate has a groove 14 that engages most of the side of the connecting rib. This groove is a connecting rib groove. When the connecting rib groove engages the connecting rib, the fixed and movable rake teeth are spaced apart, with the movable rake teeth positioned between two fixed rake teeth.

[0020] With the above-mentioned configuration of this utility model, when a sparser rake tooth is required, the assembly can be omitted; when a denser rake tooth is required, the assembly can be installed. This allows the utility model to achieve the effect of adjusting the density between rake teeth and being easy to use.

[0021] The connecting plate has a slot 14 that holds most of the side of the connecting rib, meaning that the side of the connecting plate that holds the connecting rib is larger than half a circle.

[0022] When the connecting rib slot engages with the connecting rib, the hooks of the movable rake teeth and the hooks of the fixed rake teeth are at the same position at the front end of the connecting plate, i.e., flush.

[0023] Furthermore, a C-shaped pad 141 made of rubber is installed in the connecting rib slot. When the connecting rib slot engages with the connecting rib, the C-shaped pad is in a state of holding the connecting rib tightly.

[0024] The above-mentioned features of this utility model make it easier to install the connector in the slot, and make the connecting rib more securely installed in the slot.

[0025] The C-shaped pad has a cross-section with a superior arc shape.

[0026] Furthermore, the connecting plate is also provided with a slot 15 for positioning the movable rake teeth, and the slot is formed by the slot protrusions 151 on both sides.

[0027] The above-mentioned features of this utility model can also achieve the positioning of the movable rake teeth.

[0028] In one technical solution, the locking protrusions are made of elastic steel sheets, which ensures that the movable rake teeth can be inserted between the two locking protrusions.

[0029] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
